我正在尝试用python制作一个GPS应用程序,并使用GTK Champlain作为一个小部件,同时使用clart。但是现在我在使用从OpenStreetMaps下载的本地tiles文件时遇到了问题。注意这个:
class LauncherGTK:
def __init__(self):
self.window = Gtk.Window()
self.window.set_border_width(10)
self.window.set_title("GPS")
self.window.connect("destroy", Gtk.main_quit)
vbox = Gtk.VBox(False, 10)
embed = GtkChamplain.Embed()
self.view = embed.get_view()
self.view.set_reactive(True)
self.view.connect('button-release-event', self.mouse_click_cb, self.view)
projector = Champlain.MapProjection.MAP_PROJECTION_MERCATOR
renderer = Champlain.ImageRenderer()
map_new = Champlain.FileTileSource.new_full('1','Colombia','OSM','Champlain',10,15,256, projector, renderer)
map_source = Champlain.FileTileSource.load_map_data(map_new,'Utilidades/map.osm')
self.view.set_property('kinetic-mode', True)
self.view.set_property('map-source', map_source)
#...
self.window.add(vbox)
self.window.show_all()
当我尝试运行代码时,会出现下一个错误:
Traceback (most recent call last): File "GUI.py", line 125, in LauncherGTK() File "GUI.py", line 33, in init projector = Champlain.MapProjection.MAP_PROJECTION_MERCATOR AttributeError: type object 'ChamplainMapProjection' has no attribute 'MAP_PROJECTION_MERCATOR' Press any key to continue . . .
有人知道我做错了什么吗?你知道吗
基于PyGObject的绑定drop the enum name from the enum values themselves。在您的例子中,您的代码应该使用
Champlain.MapProjection.MERCATOR
,而不是Champlain.MapProjection.MAP_PROJECTION_MERCATOR
